During the dosing period, study personnel will contact subjects by telephone on Days 7 and 21 to conduct a safety assessment. Subjects will be required to monitor their fasting blood glucose and complete a daily diary for the outpatient portion of the study between Days 1 and 28. A follow-up, safety phone call will occur 30 days following their final dose of SRT2104 or placebo (Day 58 of the study) to identify any possible additional adverse events or concomitant medications.
